If the article is any indication of what's really going to happen to Gila Bend, then the halcyon days of Sentinel are soon to be but a fond memory. Once that happens, I suspect that some of the telescopes on Kitt Peak will be considering closing down, and possibly moving to a state / country with darker skies. The light dome from Phoenix is already very threatening to Kitt Peak, so having another one much closer certainly isn't good news. /Bob > -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
